Akishino Himeka

A mysterious, black-haired girl who is actually a chuunibyo. She sent Eita letters and messages so she could finally see him. Himeka calls herself "Himekashizuka Heaven's Rain" while being in chuuni mode, and tells that her name from past life was "Burning Princess Saint Dragon Lady of Dawn". She has a one-sided crush for Eita, and says that she is his former girlfriend. However, when she isn't in chuuni mode, she has a poker face usually on, talks in third person, is a taciturn who answers usually by nodding and even throws tantrums sometimes about how Eita is only hers.
